Singapore extends the SSD holding period to four years and raises every residential tier by four percentage points

The Seller's Stamp Duty holding period for residential property was extended from three years to four years.

Applies only to residential property acquired on and after 4 July 2025, 12.00am, subject to the statutory exemptions and remissions. It does not retrospectively change the schedule applicable to an earlier acquisition cohort. HDB flats remain inside the residential SSD framework: the Government's position is that ordinary HDB owners are not affected because the Minimum Occupation Period prevents a disposal within the window, which is a statement about practical reach and not an exemption. Industrial property keeps its own separate schedule.

The Seller's Stamp Duty rate on a residential property sold within one year of purchase was raised from 12% to 16%.

Describes wholly residential property, or the residential-attributable part of mixed residential property, acquired on and after 4 July 2025. A property acquired on 3 July 2025 and sold within one year was charged 12%. The archive's source for the rate table is the release as transcribed, whose cells run together in plain text as "Up to 1 year12%16%"; that run-together form is the transcription and has not been tidied.

A residential property sold in the fourth year of ownership became liable to Seller's Stamp Duty at 4%, where the rate had been nil.

This is a year that became chargeable, not only a rate that rose. Under the schedule in force from 11 March 2017 the duty ended after three years, so a disposal in the fourth year carried none. The band covers a disposal more than three years and not more than four years after acquisition, and a disposal at exactly three years falls in the preceding tier. For a property acquired on 4 July 2025 the band opens after 4 July 2028, so no duty is assessable in it before then.

The residential Seller's Stamp Duty rate was raised by four percentage points in every tier of the revised holding period.

No before-value is stored, because the four points are a movement and not a level; the levels are carried on claims 2, 3, 5 and 6 so that each tier holds its own resulting rate. The increase describes the wholly residential schedule and the residential-attributable part of mixed residential property. Under S 480/2025 the industrial-attributable part of mixed residential property is charged at 15%, 10% and 5% across the first three years and carries no component in the fourth. The rate beyond four years remains nil, so the uniform four-point description covers the four chargeable tiers and not the schedule's final row.

The Seller's Stamp Duty rate for a holding period of more than one year and up to two years was raised from 8% to 12%.

Describes wholly residential property, or the residential-attributable part of mixed residential property, acquired on and after 4 July 2025, 12.00am.

The Seller's Stamp Duty rate for a holding period of more than two years and up to three years was raised from 4% to 8%.

Describes wholly residential property, or the residential-attributable part of mixed residential property, acquired on and after 4 July 2025, 12.00am.

The Seller's Stamp Duty rate for a holding period of more than four years remained at nil.

Stored because the release states it, and because a schedule that ends at nil is what makes the fourth-year band a boundary rather than a rate. It says only that the rate beyond four years is unchanged; it says nothing about whether the four-year boundary itself may move again, and the boundary has moved three times since 2010.

The seller-side Additional Conveyance Duty was revised by acquisition cohort: equity interests acquired between 11 March 2017 and 3 July 2025 keep the 12% rate and the three-year holding period, while equity interests acquired on and after 4 July 2025 are subject to a 16% rate and a four-year holding period.

Additional conveyance duty is computed through statutory formulas, not charged as a flat levy on the whole transaction, and where a grantor holds equity interests from both cohorts the portions are computed separately under their own rates and periods. The rate line's operators could not be read: the multiplication and division symbols inside the Article 3A formulas come out of the Gazette PDF text layer as replacement characters, so this archive holds the rate, the holding period and the cohort clause, and does not hold the formula. Re-extraction is an open question in Prevo's research record. The cohort of the equity interests decides the treatment, not the date the conveyance is executed.

For mixed residential property acquired on and after 4 July 2025 and disposed of within one year, the part attributable to an industrial purpose is charged at 15%.

No before-value is stored and none is invented. S 480/2025 amends only the date heading of the preceding paragraph (bg) and does not reproduce its rates, so the treatment of the industrial-attributable part before 4 July 2025 is not held here. Assessed at the time of execution of the instrument. A single property can carry two rates at once, so describing the mixed residential schedule as 16%, 12%, 8% and 4% describes only its residential-attributable part.

For mixed residential property acquired on and after 4 July 2025 and disposed of more than one year but not more than two years after acquisition, the part attributable to an industrial purpose is charged at 10%.

As claim 18. No before-value is stored, for the reason given there.

For mixed residential property acquired on and after 4 July 2025 and disposed of more than two years but not more than three years after acquisition, the part attributable to an industrial purpose is charged at 5%, and the fourth-year tier carries no industrial component at all.

The absence is the finding and an absence cannot be quoted. Tiers (i) to (iii) are each drafted as an aggregate of an industrial sub-paragraph and a residential one; tier (iv) has no industrial sub-paragraph, so the industrial-attributable part leaves the schedule entirely at three years. It is not charged 1% in the fourth year and it is not charged 4% either. No before-value is stored, for the reason given at claim 18.

IRAS states that there is no transition period for the change.

Relates to commencement, not to cohorts. It does not remove the statutory exemptions or the remission rules, which continue to apply where their conditions are met, and it does not override the acquisition-date rules in claims 11 and 12. A buyer who had already accepted an Option to Purchase before 4 July 2025 is on the old schedule, which is a cohort rule rather than a transition.

The date of purchase or acquisition, which determines the applicable schedule, is in most cases the date of acceptance of the Option to Purchase, the date of the Sale and Purchase Agreement, the date of the Agreement for Lease for a new HDB flat, the date of transfer to a beneficiary, or the date of transfer where none of the others applies.

Covers the ordinary cases only. IRAS sets out separate acquisition dates for transfers on divorce, transfers on inheritance, transfers of HDB flats within a family, rezoning or change of permitted use, and SERS replacement flats. Those are held in the source and are not reproduced here. Treating completion, key collection or the date of the transfer instrument as the acquisition date puts a property on the wrong schedule, because acceptance of the Option to Purchase usually precedes all of them by months or years.

An Option to Purchase that is subject to the execution or signing of the Sale and Purchase Agreement is excluded from the definition of the acquisition date.

Applies on the acquisition side. IRAS states the same exclusion separately in section C for the date of sale or disposal, and this archive does not carry the disposal-side wording.

Subject to the applicable exemptions and remissions, Seller's Stamp Duty is payable on residential properties and residential lands acquired on or after 20 February 2010 and disposed of within the applicable holding period.

Establishes the outer boundary of the regime, not the schedule, and is unchanged by this package. Residential land is included, which the release wording "residential properties" does not make obvious. The exemptions and remissions qualifying this sentence are set out in sections of the IRAS page that this archive does not hold, so none of them is repeated as a claim.

Seller's Stamp Duty is charged on the higher of the actual price or the market value of the property.

States the base of the charge and is unchanged by this package. It does not address partial interests, interests acquired at different times, or the valuation date, all of which IRAS treats separately and none of which this archive holds.

The changes took effect for all residential properties purchased on and after 4 July 2025, 12.00am.

Fixes the boundary by acquisition date only. It does not itself define what counts as the date of acquisition, which is carried by claims 11 and 12. Read alone, "effective 4 July 2025" invites the reading that sales from that date are caught; it is acquisitions from that date that are caught.

The Government stated that the revised Seller's Stamp Duty would not affect HDB owners, because of the Minimum Occupation Period for HDB flats.

A practical assessment, not a statutory exclusion, which is why it is classed as an interpretation rather than a policy fact: the reach of a rule is a construction from what the authority expects the population to do, and it would be one if a consultancy had made it. The release does not say HDB flats sit outside the SSD regime and does not state the length of the occupation period. IRAS states that the seller of a SERS replacement flat may still be liable where the sale falls inside the SSD holding period, which runs from the date of the Agreement for Lease, even where the occupation period has been met.

The Government gave as its reason a sharp increase in private residential transactions with short holding periods, and in particular an increase in the sub-sale of units that have not been completed.

The release quantifies nothing. It states a direction of travel and supplies no figure, no period and no series, so this archive attaches no number to the Government's reasoning. Two sub-sale figures circulating in commentary around the announcement were examined and refused.

In 2017 the holding period was reduced from four years to three and the rates were reduced by four percentage points in each tier, so the July 2025 change returns both parameters to their pre-2017 levels.

No structured value is stored, because the end-states of the 2017 reduction are already carried as the before-values of claims 1, 2, 3, 5 and 6, and storing them again under a second date would put one parameter in two places. The release describes the SSD parameters only. It does not say the whole March 2017 package was reversed, and that package also eased TDSR and mortgage equity withdrawal. Read as a claim about the SSD schedule, not about the 2017 round.
